Micca MB42

Why is the impedance 4-8 Ohms? Will it work with my receiver?

Micca is one of the few manufacturers that specifies the impedance of its speakers as a range, rather than a fixed nominal value. The impedance of a speaker varies depending on the frequency being played, and it is normal for most 8ohm rated speakers have impedance that dip as low as 4ohms or even lower.

While the Micca speakers work just fine with most amplifiers and receivers rated for speakers designed to handle 6ohm or 8ohm speakers, the 4-8ohm rating is a reminder to users that these speakers do have impedance that go down to as low as 4ohms and care should be taken with the listening volume so as not to damage the amplifier or speakers. Please observe the following precautions:

  • Do not play the speakers at a volume where there is audible distortion
  • If the amplifier’s output protection is triggered, immediately discontinue use
  • Ensure that the amplifier has plenty of ventilation and is not in an enclosed space
  • If the amplifier has a “4Ohm” or “High Current” mode, enable it

Micca MB42 vs MB42X, What’s the difference?

When it comes to the MB42 vs MB42X decision, it’s important to understand the similarities and differences between these two speakers. We hope this guide is helpful in making the right purchase choice.

Similarties

The MB42 and MB42X uses the same drivers, consisting of a 4-inch carbon fiber woofer, and 0.75-inch silk dome tweeter. Both use the same size enclosure and the same tuning frequency. With their grills on, it is difficult to tell them apart visually from a few feet away.

Differences

Even though the MB42 and MB42X share the same drivers and enclosure design, the MB42X represents a sizable upgrade in terms of audio performance. The most significant improvement offered by the MB42X over the MB42 is the inclusion of a 9-element crossover network. This crossover significantly improves the tonal balance and clarity of the speaker and is what’s responsible for the MB42X being such a favorite among hi-fi enthusiasts. There are also other improvements included in the MB42X, such as a flared port tube and a magnetic grill system. Lastly there is the cosmetic difference of a matte black finish on the MB42X, versus the black faux wood grain on the MB42.

The table below contains the differences between the MB42 and MB42X.
